This application is a divisional of U.S. patent application Ser. No. 15/476,303 filed Mar. 31, 2017, which is a divisional of U.S. patent application Ser. No. 15/070,238 filed Mar. 15, 2016 (now U.S. Pat. No. 9,642,364, issued May 9, 2017), which was a divisional of U.S. patent application Ser. No. 14/031,538 filed Sep. 19, 2013 (now U.S. Pat. No. 9,314,022, issued Apr. 19, 2016), which was a divisional of U.S. patent application Ser. No. 12/597,221 filed Oct. 23, 2009 (now U.S. Pat. No. 8,551,912, issued Oct. 8, 2013), which was a 371 of International Application No. PCT/EP2008/003279 filed Apr. 23, 2008, which claims priority to EP 07008370.4 filed Apr. 25, 2007, the contents of which are all incorporated herein by reference.

The present invention relates to novel fungicidal compositions suitable for control of diseases caused by phytopathogens, especially phytopathogenic fungi and to a method of controlling diseases on useful plants, especially rust diseases on soybean plants.

It is known from WO 04/35589 and WO 06/37632 that certain tricyclic amine derivatives and mixtures comprising said amine derivatives have biological activity against phytopathogenic fungi. On the other hand various fungicidal compounds of different chemical classes are widely known as plant fungicides for application in various crops of cultivated plants. However, crop tolerance and activity against phytopathogenic plant fungi do not always satisfy the needs of agricultural practice in many incidents and aspects. For example, in the past in the most important regions for soybean cultures no economicly significant phytopathogens were known. However, recently there has been an increase in severe rust infections of soybean crops in South America by the harmful fungus Phakopsora pachyrhizi resulting in considerable yield losses. Most customary fungicides are unsuitable for controlling rust in soybeans or their action against Phakopsora pachyrhizi is unsatisafctory.

Out of the above-mentioned needs of agricultural practice for increased crop tolerance and/or increased activity against phytopathogenic fungi, such as Phakopsora pachyrhizi, there is therefore proposed in accordance with the present invention a novel composition suitable for control of diseases caused by phytopathogens comprising a composition suitable for control of diseases caused by phytopathogens comprising (A) a compound of formula I

9-(3-pentylidene)-5-nitro-benzonorbornene (7.0 g, 27.2 mmol; prepared as described in Example 3) dissolved in dichloromethane (300 ml) and methanol (5 ml) was ozonized (2.8 l O₂/min, 100 Watt, corresponding to 9.7 g O₃/h) at −70° C. until a persistent blue colour was observed (after approximately 15 minutes). The reaction mixture was flushed with nitrogen gas. Triphenylphosphine (8.4 g, 32.03 mmol, 1.18 eq.) was added and the temperature was allowed to warm up to 20-25° C. After evaporation of the solvent the residue was purified on silica gel in hexane-EtOAc-3:1 to give 5.2 g of Compound 36.01 (m.p. 112-114° C.).

EXAMPLE 5

This Example illustrates the preparation of 9-difluoromethylidene-5-nitro-benzonorbornene

To a solution of dibromodifluoromethane (6.30 g, 30 mmol) at 0° C. in THF (50 ml) was added tris-(dimethylamino)-phosphane (10.1 g at 97%, equivalent to 11.2 ml, 60 mmol) in THF (30 ml) within 20 minutes. To the resulting suspension, after stirring for 1 hour at room temperature, was added dropwise a solution of 9-oxo-5-nitro-benzonorbornene (6.10 g, 30 mmol; prepared as described in Example 4) in THF (20 ml) within 25 minutes followed by stirring for 21 hours. The suspension was poured onto ice-water and extracted with ethyl acetate. Purification on silica gel in ethyl acetate-hexane-(1:4) yielded 4.675 g of 9-difluoromethylidene-5-nitro-benzonorbornene (m.p. 99-101° C.).

EXAMPLE 6

This Example illustrates the preparation of 9-Dichloromethylidene-5-nitro-benzonorbornene

Dry carbon tetrachloride (5.9 g, 33 mmol) was reacted with triphenylphosphine (14.46 g, 55.1 mmol) in dichloromethane (30 ml) at room temperature for 1 hour. 9-Oxo-5-nitro-benzonorbornene (5.60 g, 27.56 mmol; prepared as described in Example 4) in dichloromethane (10 ml) was added dropwise and stirred for 20 hours at room temperature. After aqueous work-up (ice-water) and extraction with dichloromethane, the crude product was purified on silica gel in ethyl acetate-hexane-(1:4) to obtain of the desired 9-Dichloromethylidene-5-nitro-benzonorbornene (1.83 g; m.p. 136-137° C.). Some starting material (4.06 g) was recovered.

EXAMPLE 7

This Example illustrates the preparation of 9-Dibromomethylidene-5-nitro-benzonorbornene

Carbon tetrabromide (4.66 g at 98%, 13.8 mmol) was reacted under stirring with triphenylphosphine (7.23 g, 27.6 mmol) in dichloromethane (50 ml) for 50 minutes at room temperature. 9-Oxo-5-nitro-benzonorbornene (2.8 g, 13.8 mmol; prepared as described in Example 4) in dichloromethane (10 ml) was added dropwise and stirred over night at room temperature. Aqueous work-up (ice-water) and extraction with dichloromethane followed by column chromatography (ethyl acetate-hexane-(1:9) of the crude product yielded the desired product 9-Dibromomethylidene-5-nitro-benzonorbornene (2.1 g; m.p. 153-155° C.).

According to the invention “useful plants” typically comprise the following species of plants: grape vines; cereals, such as wheat, barley, rye or oats; beet, such as sugar beet or fodder beet; fruits, such as pomes, stone fruits or soft fruits, for example apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries or blackberries; leguminous plants, such as beans, lentils, peas or soybeans; oil plants, such as rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans or groundnuts; cucumber plants, such as marrows, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruit or mandarins; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, cucurbits or paprika; lauraceae, such as avocados, cinnamon or camphor; maize; tobacco; nuts; coffee; sugar cane; tea; vines; hops; durian; bananas; natural rubber plants; turf or ornamentals, such as flowers, shrubs, broad-leaved trees or evergreens, for example conifers. This list does not represent any limitation.

The term “useful plants” is to be understood as including also useful plants that have been rendered tolerant to herbicides like bromoxynil or classes of herbicides (such as, for example, HPPD inhibitors, ALS inhibitors, for example primisulfuron, prosulfuron and trifloxysulfuron, EPSPS (5-enol-pyrovyl-shikimate-3-phosphate-synthase) inhibitors, GS (glutamine synthetase) inhibitors or PPO (protoporphyrinogen-oxidase) inhibitors) as a result of conventional methods of breeding or genetic engineering. An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding (mutagenesis) is Clearfield® summer rape (Canola). Examples of crops that have been rendered tolerant to herbicides or classes of herbicides by genetic engineering methods include glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady®, Herculex I® and LibertyLink®.

The term “useful plants” is to be understood as including also useful plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising one or more selectively acting toxins, such as are known, for example, from toxin-producing bacteria, especially those of the genus Bacillus.

The term “useful plants” is to be understood as including also useful plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising antipathogenic substances having a selective action, such as, for example, the so-called “pathogenesis-related proteins” (PRPs, see e.g. EP-A-0 392 225). Examples of such antipathogenic substances and transgenic plants capable of synthesising such antipathogenic substances are known, for example, from EP-A-0 392 225, WO 95/33818, and EP-A-0 353 191. The methods of producing such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above.

The term “locus” of a useful plant as used herein is intended to embrace the place on which the useful plants are growing, where the plant propagation materials of the useful plants are sown or where the plant propagation materials of the useful plants will be placed into the soil. An example for such a locus is a field, on which crop plants are growing.

The term “plant propagation material” is understood to denote generative parts of the plant, such as seeds, which can be used for the multiplication of the latter, and vegetative material, such as cuttings or tubers, for example potatoes. There may be mentioned for example seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes and parts of plants. Germinated plants and young plants which are to be transplanted after germination or after emergence from the soil, may also be mentioned. These young plants may be protected before transplantation by a total or partial treatment by immersion. Preferably “plant propagation material” is understood to denote seeds.

The compositions of the present invention may also be used in the field of protecting storage goods against attack of fungi. According to the present invention, the term “storage goods” is understood to denote natural substances of vegetable and/or animal origin and their processed forms, which have been taken from the natural life cycle and for which long-term protection is desired. Storage goods of vegetable origin, such as plants or parts thereof, for example stalks, leafs, tubers, seeds, fruits or grains, can be protected in the freshly harvested state or in processed form, such as pre-dried, moistened, comminuted, ground, pressed or roasted. Also falling under the definition of storage goods is timber, whether in the form of crude timber, such as construction timber, electricity pylons and barriers, or in the form of finished articles, such as furniture or objects made from wood. Storage goods of animal origin are hides, leather, furs, hairs and the like. The compositions according the present invention can prevent disadvantageous effects such as decay, discoloration or mold. Preferably “storage goods” is understood to denote natural substances of vegetable origin and/or their processed forms, more preferably fruits and their processed forms, such as pomes, stone fruits, soft fruits and citrus fruits and their processed forms. In another preferred embodiment of the invention “storage goods” is understood to denote wood.

Therefore a further aspect of the present invention is a method of protecting storage goods, which comprises applying to the storage goods a composition according to the invention.

The compositions of the present invention may also be used in the field of protecting technical material against attack of fungi. According to the present invention, the term “technical material” includes paper; carpets; constructions; cooling and heating systems; wall-boards; ventilation and air conditioning systems and the like; preferably “technical material” is understood to denote wall-boards.

In general, the weight ratio of component (A) to component (B) is from 2000:1 to 1:1000. A non-limiting example for such weight ratios is compound of formula I: compound of formula B-2 is 10:1. The weight ratio of component (A) to component (B) is preferably from 100:1 to 1:100; more preferably from 20:1 to 1:50.

It has been found, surprisingly, that certain weight ratios of component (A) to component (B) are able to give rise to synergistic activity. Therefore, a further aspect of the invention are compositions, wherein component (A) and component (B) are present in the composition in amounts producing a synergistic effect. This synergistic activity is apparent from the fact that the fungicidal activity of the composition comprising component (A) and component (B) is greater than the sum of the fungicidal activities of component (A) and of component (B). This synergistic activity extends the range of action of component (A) and component (B) in two ways. Firstly, the rates of application of component (A) and component (B) are lowered whilst the action remains equally good, meaning that the active ingredient mixture still achieves a high degree of phytopathogen control even where the two individual components have become totally ineffective in such a low application rate range. Secondly, there is a substantial broadening of the spectrum of phytopathogens that can be controlled.

A synergistic effect exists whenever the action of an active ingredient combination is greater than the sum of the actions of the individual components. The action to be expected E for a given active ingredient combination obeys the so-called COLBY formula and can be calculated as follows (COLBY, S. R. “Calculating synergistic and antagonistic responses of herbicide combination”. Weeds, Vol. 15, pages 20-22; 1967):

ppm=milligrams of active ingredient (=a.i.) per liter of spray mixture

X=% action by active ingredient A) using p ppm of active ingredient

Y=% action by active ingredient B) using q ppm of active ingredient.

According to COLBY, the expected (additive) action of active ingredients A)+B) using p+q ppm of active ingredient is

$E = {X + Y - \frac{X \cdot Y}{100}}$

If the action actually observed (O) is greater than the expected action (E), then the action of the combination is super-additive, i.e. there is a synergistic effect. In mathematical terms, synergism corresponds to a positive value for the difference of (O−E). In the case of purely complementary addition of activities (expected activity), said difference (O−E) is zero. A negative value of said difference (O−E) signals a loss of activity compared to the expected activity.

However, besides the actual synergistic action with respect to fungicidal activity, the compositions according to the invention can also have further surprising advantageous properties. Examples of such advantageous properties that may be mentioned are: more advantageuos degradability; improved toxicological and/or ecotoxicological behaviour; or improved characteristics of the useful plants including: emergence, crop yields, more developed root system, tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf colour, less fertilizers needed, less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, improved plant vigor, and early germination.

Some compositions according to the invention have a systemic action and can be used as foliar, soil and seed treatment fungicides.

With the compositions according to the invention it is possible to inhibit or destroy the phytopathogenic microorganisms which occur in plants or in parts of plants (fruit, blossoms, leaves, stems, tubers, roots) in different useful plants, while at the same time the parts of plants which grow later are also protected from attack by phytopathogenic microorganisms.

The compositions according to the invention can be applied to the phytopathogenic microorganisms, the useful plants, the locus thereof, the propagation material thereof, storage goods or technical materials threatened by microorganism attack.

The compositions according to the invention may be applied before or after infection of the useful plants, the propagation material thereof, storage goods or technical materials by the microorganisms.

The amount of a composition according to the invention to be applied, will depend on various factors, such as the compounds employed; the subject of the treatment, such as, for example plants, soil or seeds; the type of treatment, such as, for example spraying, dusting or seed dressing; the purpose of the treatment, such as, for example prophylactic or therapeutic; the type of fungi to be controlled or the application time.

When applied to the useful plants component (A) is typically applied at a rate of 5 to 2000 g a.i./ha, particularly 10 to 1000 g a.i./ha, e.g. 50, 75, 100 or 200 g a.i./ha, typically in association with 1 to 5000 g a.i./ha, particularly 2 to 2000 g a.i./ha, e.g. 100, 250, 500, 800, 1000, 1500 g a.i./ha of component (B).

In agricultural practice the application rates of the compositions according to the invention depend on the type of effect desired, and typically range from 20 to 4000 g of total composition per hectare.

When the compositions according to the invention are used for treating seed, rates of 0.001 to 50 g of a compound of component (A) per kg of seed, preferably from 0.01 to 10 g per kg of seed, and 0.001 to 50 g of a compound of component (B), per kg of seed, preferably from 0.01 to 10 g per kg of seed, are generally sufficient.

The composition of the invention may be employed in any conventional form, for example in the form of a twin pack, a powder for dry seed treatment (DS), an emulsion for seed treatment (ES), a flowable concentrate for seed treatment (FS), a solution for seed treatment (LS), a water dispersible powder for seed treatment (WS), a capsule suspension for seed treatment (CF), a gel for seed treatment (GF), an emulsion concentrate (EC), a suspension concentrate (SC), a suspo-emulsion (SE), a capsule suspension (CS), a water dispersible granule (WG), an emulsifiable granule (EG), an emulsion, water in oil (EO), an emulsion, oil in water (EW), a micro-emulsion (ME), an oil dispersion (OD), an oil miscible flowable (OF), an oil miscible liquid (OL), a soluble concentrate (SL), an ultra-low volume suspension (SU), an ultra-low volume liquid (UL), a technical concentrate (TK), a dispersible concentrate (DC), a wettable powder (WP) or any technically feasible formulation in combination with agriculturally acceptable adjuvants.

Such compositions may be produced in conventional manner, e.g. by mixing the active ingredients with at least one appropriate inert formulation adjuvant (for example, diluents, solvents, fillers and optionally other formulating ingredients such as surfactants, biocides, anti-freeze, stickers, thickeners and compounds that provide adjuvancy effects). Also conventional slow release formulations may be employed where long lasting efficacy is intended. Particularly formulations to be applied in spraying forms, such as water dispersible concentrates (e.g. EC, SC, DC, OD, SE, EW, EO and the like), wettable powders and granules, may contain surfactants such as wetting and dispersing agents and other compounds that provide adjuvancy effects, e.g. the condensation product of formaldehyde with naphthalene sulphonate, an alkylarylsulphonate, a lignin sulphonate, a fatty alkyl sulphate, and ethoxylated alkylphenol and an ethoxylated fatty alcohol.

The compositions according to the invention may also comprise further pesticides, such as, for example, fungicides, insecticides or herbicides.

A seed dressing formulation is applied in a manner known per se to the seeds employing the compositions according to the invention and a diluent in suitable seed dressing formulation form, e.g. as an aqueous suspension or in a dry powder form having good adherence to the seeds. Such seed dressing formulations are known in the art. Seed dressing formulations may contain the single active ingredients or the combination of active ingredients in encapsulated form, e.g. as slow release capsules or microcapsules.

In general, the formulations include from 0.01 to 90% by weight of active agent, from 0 to 20% agriculturally acceptable surfactant and 10 to 99.99% solid or liquid formulation inerts and adjuvant(s), the active agent consisting of at least a compound of component (A) together with a compound of component (B), and optionally other active agents, particularly microbiocides or conservatives or the like. Concentrated forms of compositions generally contain in between about 2 and 80%, preferably between about 5 and 70% by weight of active agent. Application forms of formulation may for example contain from 0.01 to 20% by weight, preferably from 0.01 to 5% by weight of active agent. Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ diluted formulations.

Surprisingly it has been found that compounds of formula (I)

wherein R₁ is difluoromethyl or trifluoromethyl and X is chloro, fluoro or bromo;

have good activity against soybean rust diseases, such as diseases caused by Phakopsora pachyrhizi and/or Phakopsora meibomiae.

Accordingly a further aspect of the present invention is a method of controlling rust diseases on soybean plants, which comprises applying to the soybean plants, the locus thereof or propagation material thereof a composition comprising a compound of formula (I).

Preferred is a method, which comprises applying to the soybean plants or to the locus thereof a composition comprising a compound of formula (I), preferably to the soybean plants.

Further preferred is a method, which comprises applying to the propagation material of the soybean plants a composition comprising a compound of formula (I).

The methods according to the invention, especially when a compound of formula (I) is used in combination with at least one compound (B) as described above, also allows good control of other harmful fungi frequently encountered in soybean plants. The most important fungal diseases in soybeans being Phakopsora pachyrhizi, Microsphaera diffusa, Cercospora kikuchi, Cercospora sojina, Septoria glycines and Colletotrichum truncatum, some of which comprise the so-called “late season disease complex”, and furthermore Rhizoctonia solani, Corynespora cassiicola, Sclerotinia sclerotiorum and Sclerosium rolfsii.

Further characteristics of compositions comprising compounds of formula (I), their application methods to soybeans and their use rates are as described for compositions comprising compounds of formula (I) and additionally at least one component (B) as described above. Their application can be both before and after the infection of the soybean plants or parts thereof with the fungi. The treatment is preferably carried out prior to the infection. When a compound of formula (I) is used on its own, the application rates in the method according to the invention are as described above, e.g. typical are rates of 5 to 2000 g a.i./ha, particularly 10 to 1000 g a.i./ha, e.g. 50, 75, 100 or 200 g a.i./ha. Compounds of formula (I) can be applied to the soybean plants once or more than once during a growing season. For use in the method according to the invention, the compounds of formula (I) can be converted into the customary formulations described above, e.g. solutions, emulsions, suspensions, dusts, powders, pastes and granules. The use form will depend on the particular intended purpose; in each case, it should ensure a fine and even distribution of the compound of formula (I).

As described above for the term “useful plant”, the term “soybean plant” includes all soybean plants and all varieties, including transgenic plants. The term “soybean plant” includes especially glyphosate tolerant soybean plants.

By “glyphosate tolerant” is meant that the plants for use in the methods are resistant to glyphosate application or tolerant of glyphosate. Glyphosate tolerant plants are made tolerant to glyphosate by conventional breeding or having a transgenic event that provides glyphosate resistance. Some examples of such preferred transgenic plants having transgenic events that confer glyphosate resistance are described in U.S. Pat. Nos. 5,914,451; 5,866,775; 5,804,425; 5,776,760; 5,633,435; 5,627,061; 5,463,175; 5,312,910; 5,310,667; 5,188,642; 5,145,783; 4,971,908 and 4,940,835. The use of “stacked” transgenic events in the plant is also contemplated.

Stacked transgenic events including additional herbicide-resistant traits such as resistance to HPPD-inhibitors, sulfonyl-ureas, glufosinate and bromoxynil are widely used and described in readily available resources. The stacked transgenic events may also be directed to other pesticide resistant traits, such as insecticide, nematicide, fungicide, etc resistance, which may be made by conventional breeding or introducing a transgenic event. Lines of transgenic glyphosate tolerant crop plants contemplated for use in the methods of the present invention include, for example, Roundup Ready® Soybean 40-3-2.

A “transgenic plant” refers to a plant that contains genetic material not found (i.e. “exogenous”) in a wild-type plant of the same species, variety or cultivar. The genetic material may include a transgene, an insertional mutagenesis event (such as by transposon or T-DNA insertional mutagenesis), an activation tagging sequence, a mutated sequence, a homologous recombination event or a sequence modified by chimeraplasty. Typically, the foreign genetic material has been introduced into the plant by human manipulation, but any method can be used as one of skill in the art recognizes. A transgenic plant may contain an expression vector or cassette. The expression cassette typically comprises a polypeptide-encoding sequence operably linked (i. e., under regulatory control of) to appropriate inducible or constitutive regulatory sequences that allow for the expression of the polypeptide. The expression cassette can be introduced into a plant by transformation or by breeding after transformation of a parent plant. As previously described a plant refers to a whole plant, including seedlings and mature plants, as well as to a plant part, such as seed, fruit, leaf, or root, plant tissue, plant cells or any other plant material, e. g., a plant explant, as well as to progeny thereof, and to in vitro systems that mimic biochemical or cellular components or processes in a cell.

If the soybean plants are glyphosate tolerant, then it is especially preferred that combinations of compounds of formula (I) and glyphosate are used. Above is given a general guidance to typical glyphosate application rates—as glyphosate is one of the compounds (B)—but the optimal rate to be used depends on many factors including the environment and should be determined under actual use conditions. Preferably, a rate of application of a glyphosate compound from about 400 g acid equivalent (ae)/ha to about 3400 g ae/ha of glyphosate is effective in controlling, preventing or treating a soybean rust pathogen, such as Asian soybean rust, in accordance with the method of the present invention. Yet more preferable are rates of application range from about 800 g ae/ha to 1700 g ae/ha. Generally, glyphosate-containing compositions can be applied, if applied only once, at a rate of 960 g ae/ha; if applied twice the rate can vary from 1200 to 1680 g ae/ha. When more than one application of glyphosate-containing compositions to the soybean plants are performed, it is not necessary that all glyphosate-containing compositions contain also a compound of formula (I). The rates and number of glyphosate-applications may vary according to the particular conditions. Preferably, glyphosate-containing compositions are applied three times with an application rate of 960, 720 and 400 g ae/ha respectively. In said embodiment of the invention, the present invention also provides a method for controlling undesired vegetation, such as harmful weeds, and controlling, preventing or treating soybean rust diseases in a field of glyphosate tolerant soybean plants. Preferably, the application or applications are timed for effective weed control and effective soybean rust control, prevention or treatment in the treated soybean plant. For example, without limitation, a glyphosate-containing composition is applied at a time when the application controls the weeds within the field; a second glyphosate-containing composition is applied at a time when the glyphospate tolerant soybean plants are either at risk of infection or have already been infected by a soybean rust disease, said second glyphosate-containing composition additionally comprises at least a compound of formula (I). Another application of the second glyphosate-containing composition can also be envisaged to further prevent infection.
